Should the Oil Drain Plug Washer Be Replaced?
2 Answers
The washer for the drain plug can be purchased and replaced separately. Theoretically, it should be replaced every time it is removed and reinstalled. Therefore, it is best to purchase and replace it during every oil change to avoid unnecessary trouble caused by oil leaks that would require further handling. The washer needs to be replaced: If it is not replaced, after adding new oil, be sure to run the engine and carefully observe whether there is any oil leakage. If no leakage is found upon inspection, the issue is not significant. If you plan to reuse it, it is recommended not to exceed three uses. The drain plug washer should be replaced—generally, it needs to be replaced once it is damaged. Replacement is necessary if it fails to meet sealing standards: During routine oil changes, the washer is typically not replaced because there is no strict time limit for its replacement. Changing the oil only requires replacing the oil filter. This issue only occurs in a few vehicles. If the washer material is soft, it can provide better sealing when tightened due to its flexibility. However, because it is soft, it may deform after the second use and fail to meet the original sealing standards.
I remember when I changed the engine oil for the first time, that small washer made me hesitate whether to replace it. My mechanic friend told me it's a crucial component for preventing oil leaks - repeated use can cause wear and deformation, leading to poor sealing. Later, I tried reusing it and noticed oil dripping, forcing me to retighten the bolt. Now I always replace it with a new washer because they're inexpensive and easy to find at most auto parts stores. Regular replacement ensures the engine stays leak-free and prevents more expensive repairs later. For everyday car owners, developing this habit is simple - just check during each oil change. It takes mere minutes but guarantees peace of mind on the road.
